[0002] Mining drill bits are specialized tools used for drilling during the mining process. Their main functions include breaking rocks, exploring resources, and borehole measurement.
[0003] Mining drill bits are classified into diamond drill bits, carbide drill bits, impact drill bits, and composite drill bits. The production of mining drill bits includes design, material selection, manufacturing, and quality control. The manufacturing of mining drill bits includes steps such as cutting, grinding, and heat treatment. Between each process, lifting equipment is needed to lift and move the workpiece.
[0004] In existing mining drill bit lifting technologies, hooks and slings are typically used for lifting. During the lifting process, the drill bit may shake, causing it to fall out of the lifting device and resulting in damage. To address this, we propose a new type of mining drill bit lifting device.

[0009] This step, through the arrangement of servo motors, lead screws, and clamping frames, forms a drill bit hoisting and clamping structure, which realizes the function of clamping and fixing both ends of the drill bit.

[0029] The embodiments of this utility model will be further described below with reference to the accompanying drawings.
[0030] Example:
[0031] like Figures 1-4 As shown, it includes a lifting plate 1, a clamping assembly in the middle of the lifting plate 1, a fixing assembly through the clamping assembly, a restraining assembly on the side wall of the lifting plate 1, and a lifting assembly on the top of the lifting plate 1.
[0032] The working principle of the above technical solution is as follows:
[0033] During operation, the lifting assembly is hung on the overhead crane, the crane is started to move the lifting plate 1 above the drill bit workpiece to be lifted, the height of the lifting plate 1 is adjusted so that the clamping assembly is horizontal with the workpiece and clamps the workpiece. When the clamping assembly clamps the workpiece, the fixing assembly fixes the workpiece on the clamping assembly, and then the restraint assembly is used to lift the middle of the drill bit. The crane is then moved to the designated location.
[0034] In another embodiment, such as Figure 2 As shown, the clamping assembly includes a servo motor 11, a lead screw 12, and a clamping frame 13. The servo motor 11 is fixedly connected to the end of the lifting plate 1, the lead screw 12 is rotatably connected to the middle of the lifting plate 1, and the end of the lead screw 12 is fixedly connected to the transmission end of the servo motor 11. The clamping frame 13 is slidably connected to the middle of the lifting plate 1. A pair of servo motors 11 are provided in the middle of the lifting plate 1 and are symmetrically arranged. The clamping frame 13 cooperates with the lead screw 12 lead screw nut pair.
[0035] During operation, the lifting plate 1 moves above the workpiece, the clamping frame 13 moves to both ends of the workpiece, the servo motor 11 is started, the servo motor 11 drives the lead screw 12 to rotate, the lead screw 12 drives a pair of clamping frames 13 to move closer to each other, inserting both ends of the drill bit workpiece into the clamping frame 13 and clamping it.
[0036] In another embodiment, such as Figure 3 As shown, the fixing assembly includes a pressure rod 2, a spring 21, a first V-shaped clamp 22, and a second V-shaped clamp 23. The pressure rod 2 is slidably connected to the middle of the clamping frame 13. The first V-shaped clamp 22 is fixedly connected to the end of the pressure rod 2 away from the lifting plate 1. The second V-shaped clamp 23 is fixedly connected to the bottom of the inner side wall of the clamping frame 13. The spring 21 is sleeved on the outer side wall of the pressure rod 2 away from the first V-shaped clamp 22.
[0037] During operation, when the workpiece is inserted into the clamping frame 13, the pressure rod 2 is pulled to drive the first V-shaped clamping block 22 upward, the spring 21 is stretched, and the workpiece is placed on top of the second V-shaped clamping block 23. After the clamping frame 13 clamps, the pressure rod 2 is released, the spring 21 drives the pressure rod 2 and the first V-shaped clamping block 22 to return to their original positions, and the first V-shaped clamping block 22 and the second V-shaped clamping block 23 fix the workpiece in the middle of the clamping frame 13.
[0038] In another embodiment, such as Figure 4 As shown, the restraint assembly includes an elastic band 3 and an anti-slip strip 31. The end of the elastic band 3 is detachably installed on the side wall of the lifting plate 1. Multiple sets of elastic bands 3 are provided on the side wall of the lifting plate 1 and are arranged symmetrically. The anti-slip strip 31 is fixedly connected to the inner side wall of the elastic band 3. Multiple sets of anti-slip strip 31 are provided on the inner side wall of the elastic band 3 and are evenly distributed on the inner side wall of the elastic band 3.
[0039] During operation, before hoisting the workpiece, the elastic band 3 is opened. After the workpiece is clamped between the clamping frames 13, the elastic band 3 is wrapped around the workpiece and fixed to the side wall of the hoisting plate 1. The anti-slip strip 31 increases the friction between the elastic band 3 and the outer side wall of the workpiece.
[0040] In another embodiment, such as Figure 1 As shown, the hoisting assembly includes a pull ring 4 and a pull rope 41. One end of the pull rope 41 is fixedly connected to the top of the hoisting plate 1. A pair of pull ropes 41 are provided on the top of the hoisting plate 1 and are arranged symmetrically. The side wall of the pull ring 4 is fixedly connected to the end of the pair of pull ropes 41 away from the hoisting plate 1.
[0041] During operation, the pull ring 4 is hooked onto the crane hook. The crane drives the pull ring 4 to rise, and the pull rope 41 is tightened, which in turn moves the device and the workpiece.
[0042] In another embodiment, such as Figure 3 As shown, a first gasket 5 is fixedly connected to the bottom of the first V-shaped clamp 22 away from the pressure rod 2. A pair of first gaskets 5 are provided at the bottom of the first V-shaped clamp 22. A second gasket 51 is fixedly connected to the top of the second V-shaped clamp 23. A pair of second gaskets 51 are provided at the top of the second V-shaped clamp 23.
[0043] During operation, when the first V-shaped clamp 22 and the second V-shaped clamp 23 clamp and fix the workpiece, the first gasket 5 and the second gasket 51 contact the outer wall of the workpiece, increasing the friction between the first V-shaped clamp 22 and the second V-shaped clamp 23 and the workpiece.
[0044] In another embodiment, such as Figure 3 As shown, a rubber plate 6 is fixedly connected to the inner wall of the clamping frame 13 away from the elastic band 3, and the rubber plate 6 is provided on the inner wall of both clamping frames 13.
[0045] During operation, when the clamping frame 13 clamps the workpiece, the rubber plate 6 contacts the end of the workpiece to buffer the workpiece, reduce the possibility of the workpiece colliding with the clamping frame 13 when it is clamped, and improve the stability of the workpiece when it is clamped.
[0046] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
